Coded Instrument Flight Procedures (CIFP)

The Coded Instrument Flight Procedures (CIFP) is a dataset modeled to the Airlines Electronic Engineering Committee (AEEC) Aeronautical Radio Incorporated (ARINC) Navigation System Data Base (NDB) international standard (ARINC 424). The CIFP data can be used to support both En route and Terminal GPS navigation. Currently, ARINC 424 version 18 is provided. Version 18 supports WAAS RNAV (GPS) Approaches. The CIFP is raw ARINC data. It will require additional processing before it can be loaded into an avionics system. See the CIFP Readme File (PDF) for additional information.

The CIFP is updated every 28 days.
